SAN DIEGO (KGTV) -- For over a decade, SDSU associate professor of chemistry Gregory Holland has been researching spiders and particularly black widow’s silk.They’ve come to the realization, through their research, that the properties of black widow silk are stronger than steel and tougher than the Kevlar in bulletproof vests.Gregory Holland, SDSU associate professor of analytical chemistry and Northwestern chemistry professor Nathan Gianneschi said their collaboration shows the organization of the molecules involved in silk production is more complex than previously thought.There are companies that use synthetic spider silk but its the specific black widow spider silk that has the top tier benefits.“The synthetic spider silk its not a bad material, its just not as good as the real thing," Holland said.Holland says the company that creates synthetic silk actually has partnerships with Adidas and Patagonia. "The most important thing is a spider does it low energy, environmentally friendly. It’s just protein water and salt”.Once they reach the point where they’re able to identically replicate the silk of a black widow spider, the artificial version could be used in building materials for bridges or environmentally friendly replacements for plastic.Black widows (Latrodectus hesperus) spin a lightweight thread much stronger than that of other spider species, with draglines that can stretch an extra 25 percent of their length before snapping.The composition of the spun silk fibers was previously identified, but the structure of the proteins involved in producing them has been more of a mystery, now one step closer. 1650

SAN DIEGO (KGTV) - Family and friends of a disabled Clairemont woman are making a plea for the arrest of a hit-and-run driver who left her with serious injuries.Last week, a beaming Delores Odom appeared at a surprise party for her 59th birthday. One of the attendees was her friend and neighbor Maritza Gates. "She was so happy that day. It breaks my heart to see her in the hospital now in so much pain," said Gates. On Saturday just before 6:30 p.m., Odom decided to take a walk to grab dinner. She was crossing westbound on Genesee Avenue in the south crosswalk when she was hit by a vehicle that had been going westbound on Derrick Drive and made a left turn to southbound Genesee Avenue, according to police.Odom's daughter Brianna says her mother broke her back in two places. Odom has feeling in her toes, but still faces possible paralysis and requires complicated back surgery. Her recovery and rehabilitation is made more challenging because of a decades-old diagnosis of multiple sclerosis. "There's a special place for people like that. I don't understand how you could hurt someone and then leave them. My mom is one of the nicest people ever. You don't know someone's story when you leave them to die on the street," she said.Police say there is no description of the vehicle and are looking for witnesses. Anyone with information is asked to call Crime Stoppers at 1-888-580-8477.A Gofundme campaign has been set up to help with expenses. 1462
